Here's how to escape a flooding vehicle

If you're ever in a car accident that results in the car sinking, you only have seconds to react and save your life. Here's what to do.

Following is a transcript of the video:

Reaction time and speed are key for survival. A sinking car will not immediately submerge, which means there's a small window of opportunity to act.

Don't try to open the door. Water pressure makes this extremely difficult to do. And even if you could open the door, this would allow more water to come in and make y our car sink faster. Instead, quickly roll down your side window, unbuckle yourself, and climb out. If you were too slow to react, the water pressure could pin your doors and windows shut. That means you'll have to break a window. Don't try the car's front windshield as it's built to resist impacts. Instead, go for the side windows. Use your foot and kick at the top of the window or remove the headrest from your seat and jam it where the window meets the door.

You can also use a glass breaking tool like ResQMe to quickly break the window. It can easily be stored in the glove compartment or on your keychain. If the car is upside down and your seatbelt is locking you in, the tool can even cut you free.

After breaking the window, immediately take a deep breath of air and swim out through the rushing water toward safety.
